Not entirely. I started by turning of IK on Miki 3's legs, zeroing her and dropping her to the floor before importing the stiletto.obj and moving it into position. I also had to edit the CR2 and replace the word sandals with stilletos with search and replace so that the item showed up with the right name when loaded, but that didn't really affect the functionality of it. I also need to remove some extraneous material zone names from the CR2 associated with the original Sandals, but again, they don't affect anything even if you apply materials to them. It's not perfect.
